useAiEvents stopListener 补 clearStreamWatchdog()(原漏清 _streamWatchdog 计时器,卸载后 130s onStreamTimeout 仍写 state);AiChat onBeforeUnmount 补 store.stopListener()(原全仓零调用 listener+watchdog 永久泄漏)。R1 双注册经核查 App.vue:94 v-if 互斥(detach 卸载主窗口 AiChat)同一时刻仅一窗口持活 listener,无真实双消费,不加去重标志避免过度防御(留后续:互斥逻辑改变则需去重或后端 emit_to 定向)。批8 wsyxw19ai,vue-tsc 0
